APPARATUS FOR DISCHARGING COKE.

SPECIFICATION forming part of Letters Patent No. 793,355, dated June '27, 1905.

Application filed March 25,1904. Serial No 199,995.

To all wit/Mn it may concern:

Be it known that I, J osurn D12 Bnouwna, manager of the Bruges Gas lVorks, residing at Brnges, Belgium, have invented Improvements in Apparatus for Discharging Coke, of which the following is a specification.

This invention of improvements in apparatus for discharging coke from through gasretorts relates to mechanism by which coke may be pushed out of gas-retorts which are capable of being opened at both ends and which are commonly called through-retorts to distinguish them from other forms of retorts in which the retort is formed with a solid end or has a division-wall built in the middle to divide the retort into two separate parts.

The object of this invention is to provide a simple and convenient apparatus for pushing the coke from or out of through-retorts in gasworks; and the chief feature of the invention consists in the construction of the pusher.

In carrying this invention into practical effect the pusher is carried in a frame adjustably pendent from a carriage arranged to run on the floor of the retort-house and at any desirable distance from the ends of the retorts or on an overhead railway extending along the front of the retorts, also at any desirable distance from the ends of the retorts. This car riage is provided with vertical guides between which the pusher and its frame can be raised or lowered according to requirements. pusher consists of a rigid rod of comparatively short length provided with a plate at the end to act as a pushing-plate. The other end of the rigid rod is connected with a series of links which form a rearward continuation of the rigid rod or pusher. These links, as

well as the rigid rod, are formed each with a recess on the top to contain Water, and on the under side the rigid rod and the links have teeth and virtually form a jointed rack. The links are Wound over pulleys or suitable guides in the frame or round a disk carrier, the axle of which is mounted in suitable guides .or hearings in the pusher-frame. To project or withdraw the pusher, a toothed wheel gearing with the jointed rack is driven through a worm-wheel on its shaft by a worm on a shaft parallel with the frame, the worm-shaft being The actuated by suitable gearing from a prime mover of some suitable form, preferably clcc tric, or by any other source of power.

' I do not confine myself to the exact details of the driving mechanism mentioned above, but use any more suitable arrangement. For instance, the worm-shaft can be provided with a friction clutch mechanism by which the proper belt and pulley to project or withdraw the pusher is brought into operation as and when required by a suitable lover, or I can make use of a reversing electric or other motor. I can also manage the gearing to drive from the motor-shaft by means of a train of spurpinions and wheels and flexible chain to the axle of the rack-pinion before mentioned.

In order that this invention may be more readily understood and more easily carried into effect, I will proceed to describe the same with reference to the accompanying drawings, in which I show the arrangements as follows: I

Figure l is a side view'of my invention as arranged for being supported on rails laiddn or on the floor and with the driving mechanism actuated by means of a reversing electric motor. Fig. 2 is a side view of the pusher in its guides in the frame. Fig. 3 is a similar view of the pusher wound up on a disk carrier in a spiral. Fig. I is aside view, on an enlarged scale, of a link of the jointed rack. Fig. 5 is a cross-section of the same. Fig. 6 is a plan view of the same.

7 Referring to Figs. 1, 2, 3, E is the rigid rod; F, the plate. E, the rigid rod, is connected at the other end toa series of links H H, joint-- ed in such 'a manner that they can only fold up in one direction. Each link is formed with a recess L in the top to contain water, and on the under side there are teeth, Fig. 4, to gear with the pinion D, Fig. 2.- The links are guided along the carrier G, Fig. 2, and coiled along the suitable guides of the pusherframe G. The links can equally well be wound round a disk carrier in spiral, Fig. 3,

' the axle of which is mounted in suitable guides in the pusher-frame G. To project or withdraw thepusher, a toothed wheel D, gearing with the jointed rack E and H H, is driven through a worm-wheel C on its shaft bye.

Worm B on a shaft parallel with the frame (1+,

the Worm-shaft being actuated from a prime mover A of some suitable form, preferably electric, as shown in Fig. 1, in which case the direction of the rotation is changed by reversing the electrical current.

I claim as my invention 1. An apparatus for pushing coke from through-retorts, consisting of a rigid rod-bar, toothed links attached thereto, forming a rack flexible in onedirection only, means on which the rack inayhe folded up, and an operatingpinion meshing With said rack.

2. An apparatus for pushing coke from through-retorts, consisting of a rigid rod-bar, toothed links attached thereto forming a rack flexible in one direction only, curved guides on Which the flexible rant: may folded my and an operating-pinion nieshm; "it'll said rack.

An apparatus for pushing coke from th rough-retort-s, consistingof a rigid rod-bar, and jointed cup-shaped links attached thereto forming a flexible rack, said links adapted to hold Water for the purpose of keeping the parts cool, substantially as dcscriocd. Y

In testimony whereof I have signed my name to this specification in the presence of two subscribing- Witnesses. c
